"Model Grandson" in Dying Light 2

This quest can be picked up after the story mission "A Place I'll Call Home". As a reward, you will receive 3000 combat points and the same amount of parkour points.

To start the mission, talk to the confused old lady northwest of the Tick Windmill. Go to the marker in the north, go inside and interact with the renegade's corpse to get a cure for the woman. Go back to her and chat on different topics. You can repeat the conversation and find out more interesting details about her life. It doesn't affect anything.
